Abstract The coastline of the Korean Peninsula is influenced by three major oceanographic ecoregions, including estuarine Yellow Sea ecoregion on west coast, warmer and saline East China south cold east coast. influence these marine ecoregions distribution intertidal barnacles has not been extensively studied. present study examines biogeography thoracican from shallow subtidal zones, along coasts Korea. Twenty-one species in seven families were identified, coral-associated barnacles. Species composition varied significantly ecoregions. Multivariate analysis showed barnacle assemblages significant among although there are large overlaps clusters between species, Fistulobalanus albicostatus , occurred mainly ecoregion; warm-water Tetraclita japonica sponge inhabiting Euacasta dofleini observed cold-water Balanus rostratus Perforatus perforatus found ecoregion. Four invasive recorded European expanded its range northward nine years earlier. Chthamalus dalli Semibalanus cariosus previously ecoregion, absent survey. A trend increasing seawater temperatures waters may have a impact enhance invasion P .
